LUBRICATING APPARATUS.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed March 16, 1911. Serial No. 614,832.

To all whom it may concern:

Be it known that I, CHARLES S. BAVIER, a citizen of the United States,and a resident of the borough of Manhattan, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Lubricating Apparatus, of which the following is a specification.

This invention relates to improvements in lubricating apparatus; and inparticular it relates to improvements in that type of lubricatingapparatus, whereina terminal resistance valve isprovided, so that thelubricant, being delivered by the resistance valve into the powergenerating medium as an impalpable spray, can not coalesce into dropsbefore it is distributed over the said surfaces. When a lubricant isthus delivered and distributed, the maximum results of lubrication areattained with the minimum quantity of lubricant, and the evils arisingfrom excessive use of lubricant are avoided.

The present invention is particularlyapplicable, as hereinbefore stated,to lubricating apparatus of the aforesaid type, and is adapted to beused with engines driven by air, steam, oil, gas or any other powergenerating medium.

Thepresent invention also provides apparatus so constructed and arrangedthat various parts can be removed iior cleaning, and various parts canbe changed or re- .paired without permitting the power generating medium'to escape, and scald or burn the workman.

It also provides means for filtering the lubricant and any substancewhich may be mixed therewith'before the lubricant or mixture reaches thefiner passages in the in- 40 terior of the valve casing, therebydiminishing the liability of the clogging the valve.

The invention is also designed and con structed so that it willeffectively deliver the minimum quantity of lubricant into the -powergenerating ;medium, even drop by ing a lower temperature of vaporizationthan the oil, and it is designed to raise the oil or the mixture to avery high temperat-ure when desired, soas to discharge the lubricantinto the power generating medium' with a kind of explosive violence,which tears the particles of lubricant into fine spray as they enter thepower generating medium.

Other advantages of the invention will be apparent from the descriptionand claim hereinafter contained.-

Referring to the drawings which accompany the specification to aid thedescription, Figure 1 is an elevation of the apparatus. Fig. 2- is alongitudinal section, in closed position, with certain parts inelevation, through the axis of the casing, on a larger scale. Fig. 3 isa cross section on the plane of the line 33 of Fig. 2, but showingcertain parts in elevation. Fig. 4e is a cross section on the plane ofthe line 44 of. Fig. 2..

For clearness and conciseness of descrip-' tion, I shall hereinafterdesignate the outer shell including the parts A, B, C, and theiraccessories collectively as the casing, and the parts D, E, F and theiraccessories collectively as the valve, sometimes also referring to thepart D as the valve proper. Said casing, of any suitable material,comprises the nozzle A, preferably provided with an extension at adaptedto project well into the chamber containing the power gen cratingmedium, and which chamber maybe a steam cylinder, the cylinder of an oilor other engine, the valve chest thereof, or the steam pipe or otherconduit conveying the power generating medium to the engine; and thepart lettered G in Fig. 1, indicates diagrammatically a wall of thechamber into which the lubricant is delivered. Said nozzle A is threadedto engage threads on' said wall, the joint being made tight in anysuitable manner. Said extension a is provided with an outlet '1) forlubricant, preferably arranged to l discharge directly into said powergenerating medium, so that the lubricant spray can not coalesce again'Also threaded into nozzle A, within said bonnet B, is the ported sleeveO, and in the annular space between said bonnet and said sleeve is thefilter H consisting preferably of a hollow metal cylinder with one endclosed and perforated peripheral wall. For convenience of construction,I prefer to place in said nozzle A, a'cylindrical lining j, securelyheld by having its flaring end k clamped between the conical end of saidsleeve C and conical shoulder on the inside of said nozzle A, saidlining being of such internal diameter as to provide only a smallannular space around the valve stem.

E; said construction forming, when desired, a very effective heatingchamber. Said valve preferably comprises the head, or valve proper D,the valve stem E, flanged sleeve F, and accessories to be hereinafterdescribed. Said head D is a slide valve opening outwardly preferablycylindrical, working with oil tight fit in said nozzle A, and seating onthe end of said lining j preferably at the inner edge of the outlet 6which is preferably of circular form. Thus, as said valve begins toopen, the inter-section of the inner face of head D with the peripheralarc of said outlet 7) forms a most minute opening, thereby providing forthe effectivedischarge of the most minute quantity of lubricant, even asingle drop. Said valve is located sufficiently near the chamber towhich the lubricant is to be supplied, so

that said lubricant shall not coalesce into drops after discharging fromsaid valve.

,Said valve stem E is provided with the flanged sleeve F, which workswith oil-tight fit in said sleeve C, a spring 0 normally tending to holdthe valve proper closed.

The outer end of sleeve F is preferably of somewhat greater diameterthan the inner end of said sleeve, and greater than the diameterof saidhead D, and said lining y is practically of the same internal diameteras said sleeve C. Said pipe f, g, one or both, will be connected withsuitable source or sources of supply, and with a suitable pump, orforcing apparatus, not shown, to force the lubricant or mixture into thevalve casing under pressure sufiicient to open the valve proper whennecessary.

The operation is as follows: If lubricant alone is used, as oil, usuallymixed with much air, the inlet 6 will be closed by any suitable plug inthe ordinary manner. Then the pump will force the lubricant and air intothe chamber B, and the lubricant and air will filter through filter H,and by the ports in sleeve G into the interior of said sleeve and intothe annular space between lining y and valve stem E. When the pressureon the valve becomes suflicient valve proper D will open, the lubricantand any air mixed with it flying through the minute opening formed assaid valve proper opens, as a finely atomized spray, and entering thepower generating medium in that form, before it can again coalesce intodrops, and being distributed by said medium over all the surfaces to belubricated.

If a substance having a lower temperature of vaporization than thelubricant is to be mixed therewith, the mixing may be performed beforethe lubricant enters the valve casing, or it may be performed withinsaid casing. In the latter case, both inlets d and 6 will be connectedwith pipes connecting respectively with a source of supply of lubricantand of other substance, and with a pump or forcing device, and themixture will then take place within said chamber B, the filtration andthe admission of the-mixture within the lining j occurring ashereinbefore explained. But there is only a thin film of the mixture inthe annular space within said lining j, and this film is quickly raisedto a high temperature, with corresponding high pressure, by the heatednozzle a,-which is heated by the hot power generating medium, and now,when the valve proper opens, the said substance, as it were, exploding,tears the particles of lubricant asunder as they enter the powergenerating medium, and converts them into an impalpable mist, which isdelivered by said medium to the surfaces to be lubricated. Y

It will be seen from the foregoing descrip-,

tion that the bonnet B, and filter H, and even the sleeve C, can beremoved for cleaning, etc., without any danger of the escape of the hotpower generating medium, or of burning or scalding the workman.

. It will be understood that while the inven tion is especially adaptedto be used'wit-h highly heated power generating mediums,

such as steam or hot explosive gases, it is In a lubricating valve, thecombination of a cesing, a resistance valve therein, a valve Signed atNew York city in the county of sbem E thereof, a, lining j in saidcasing New York and State of New York this 14" 10 around said valvestel? enlflgdapted to fan: clay of March, A.
